JOSEPH ROLLS, OF NEXV YORK, N. Y.

CARPET-DUSTER.

Specification of Letters Patent No. 30,590, dated November 6, 1860.

T 0 @ZZ whom it 'may concern:

Be it known that I, JOSEPH ROLLS, of the city, county, and State of New York, have invented a new and Improved Machine for Dusting Carpets; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure 1 represents a transverse vertical section of this invention, the line m, a2, Fig. 2, indicating the plane of section. Fig. 2 is a trent elevation of the same.

Similar letters of reference in both views indicate corresponding parts.

The object of this invention is to eii'ect the dusting of a carpet simultaneously on both sides by exposing it to the action of alternately acting rotary hinged beaters, and of alternately acting revolving brushes in such a manner that both sides of the carpet are first well beaten and afterward brushed oii perfectly clean, each of the beaters and of the brushes acting as a point of resistance during the action of the other beaters or brushes.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation with reference to the drawing.

The beaters A, A', consist of slats with rounded backs and hinged to the tour arms a, a', of crosses B, B', which are secured to These sh atts have their bearings in the frame C, and they are connected by gear wheels I), so that they rotate in opposite directions, as indicated by arrows marked upon them in Fig. l. Above the cross-shaped rollers B, B', and connected to the four arms of similar cross-shaped rollers E, E', are the brushes 0,. c', and the rollers E, E', are secured to axles d, CZ', which are connected by gear-wheels e, in such a manner that they rotate in opposite directions. Both the rollers B, B', and the rollers E, E', are arranged in such relation to each other', that the arms of the rollers B and E, are placed at angles of 45 degrees toward the arms of the rollers B', and E'. By these means the action of the beaters and of the brushes is rendered alternative, first taking etect on one side and then on the other.

The carpet is taken up byl a roller F ,which has its bearings in the upper part of the frame C, and to which a slow rotary motion is imparted by a belt passing over the pulley G, that is secured to the axle of the roller F. This roller is intended to be in close proximity to the brushes c, o', and one end of the carpet is fastened to the same by means of tacks or in any other suitable manner, and the machine is started. By the motion of the roller F, the carpet is slowly drawn through between the beaters A, A', and brushes c, o', and both sides of said carpet are exposed to the alternating blows of the beaters, and to the alternating action of the brushes.

By referring -to Fig. l, in the drawing, it will be noticed that the beaters on one side of the carpet support the same while the beaters take action on its other side, and in the same manner the brushes on one side bear on the carpet and hold it, to a cert-ain extent, while the brushes on the other side act.

The frame C, is made sufficiently long to admit carpets of any width, and it will be easilyI understood that the brushes and the beaters can be made in sections, which may be found to be of advantage especially as far as the beaters are concerned, and the carpet also may be exposed to more than one set of beaters, and to more than one set of brushes it it should be found necessary to effect a perfect dusting of the same by one operation.

The machine is very simple in its construction, it is easily operated, and all its parts are so constructed that they do not easily get out of repair.

I do not claim broadly the employment of rotary beaters and of rotary brushes for the purpose of dusting carpets; neither do I claim in itself the dusting of a carpet simultaneously on both sides by machinery, but

Having thus fully described my invention, what I claim vas new, and desire to secure by Letters Patent, is:-

The combination of the beaters A, A, and a thorough dusting 'of the carpet is brushes c, c', and take-up roller F, substaneeeted. tially as herein described, so that While the carpet is drawn through between the beaters JOSEPH ROLLS' 5 and the brushes both sides of the same are Witnesses:

rst exposed to the action of the beaters, M. M. LIVINGSTON,

and afterward to the action of the brushes, L. W. BENDR.
